Double-loop buckle



Nov. 19, 1935. J. sALlsBuRY DOUBLE LOOP BUCKLE Filed July 24, 1935 Patented Nov. 19, 1935 UNITED STATES PATENT OFFICE DOUBLE-LOOPV BUCKLE Jessup Salisbury, Mount Carmel, Conn., assigner to The American Buckle Company, Haven, Conn., a corporation West This invention relates to an improvement in slide buckles of the type known as double-loop buckles, from the fact that they are designed to be used with overalls having a pair of buttons for each buckle, the object of my present invention being to produce a double-loop buckle 0f superior appearance and convenience, and constructed with particular reference to avoiding the escape of the buttons when tension on the strap is removed, as when the wearer bends forward.

With these ends in view, my invention consists in a double-loop buckle having certain details of construction as will be hereinafter described and particularly recited in the claims.

In the accompanying drawing:

Fig. l is a view in front elevation of a buckle constructed in accordance with my invention and shown as in use;

Fig. 2 is a view in vertical section on the line 2-2 of Fig. 1;

Fig. 3 is a corresponding View on the line 3-3 of Fig. 1;

Fig. 4 is a detached view in front elevation of the buckle;

Fig. 5 is a reverse View thereof; and

Fig. 6 is a view thereof in horizontal section on the line 6 6 of Fig. 4.

In carrying out my invention, the buckle is struck from a single piece of sheet-metal to form an upper bar I0, a middle bar I I and a lower bar I2, these bars being separated by parallel slots I3 and I 4 through which the shoulder-strap I5 is passed, as clearly shown in Figs. 2 and 3. The lower bar I2 aforesaid is symmetrically struck forwardly on opposite sides of its center to provide clearance-bows I3 for the easy introduction of the pair of buttons I'I attached to the garment I8. The lower portion of the buckle is struck up to form two complementary button-loops I9, the

open upper ends or throats of which are slightly inclined toward each other. Conversely, the closed lower ends of the said loops are somewhat farther apart thanv their open upper ends, as clearly shown in Figs. l, Al and 5, whereby, when a pair of buttons are seated in the closed bottoms of the loops, they will not ride out of the same unassisted. These loops IS are separated by an upstanding reach 20, the upper edge of which is substantially semicircular in shape and formed with a crescent-shaped bevel 2 I, which is centered with the depression 22 formed in the lower bar I2 between the clearance-bows I6 thereof.. The crescent-shaped bevel 2l of the reach 20 lies between two inwardly-bent button-guiding lugs 23, the inner edges whereof are respectively inclined toward each other to correspond to the inward inclination of the upper ends of the respective loops I9. The said button-guiding lugs 23 coact with the respective ends of the bevel 2| to guide the respective buttons into the respective loops I9, the 5 slight inclination of which toward each other assists in holding the buttons against escape.

The metal entering into the buckle is struck up to form, upon its rear face, a bearing-flange 24 located at a right angle to its plane and extend- 10 ing completely around its inner and outer edges and the bars IU, II and I2, save only that the flange is flattened upon the ends or high points of the button-guiding lugs 23. This flange 24, standing, as it does, at a right angle to the plane 15 of the buckle, provides a bearing for the Shanks 25 of the buttons, the downward draft of which falls upon the said flange. The flange also provides a bearing for the shoulder-strap as it is woven through the buckle, as shown in Figs. 2 20 and 3.

By constructing the buckle as shownand described, with particular reference to inclining the throats or open upper ends of. the loops slightly toward each other, whereby their closed lower 25 ends are correspondingly separated from each other, and forming the interposed reach with a crescent-shaped bevel coacting with similar bevels upon the button-guiding lugs which lie athwart the' open upper ends of the loops, the buckle is 30 very readily engaged by the two buttons by the feeling of the wearers hand alone, even thoughthe wearer does not see the buckle itself. When the two buttons slip into place in their respective loops, they are stabilized therein by the inclina- 35 tion away from each other of the closed lower ends of the loops. On account of the inclination of the loops as described, the shanks of the respective buttons are slightly separated from each other, so that, if the wearer bends forward and the draft 40 between the buttons and the buckle is removed, the buttons are checked in their movement toward each other and so are prevented from escaping from the buckle.

The invention may be carried out in other spe- 45 cific ways than that herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiment is, therefore, to be considered in all respects as illustrative and not restrictive, and all 50 changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.

I claim:

l. As a new article of manufacture, a one- 55 piece double-loop buckle having an upper, a middle, and a lower bar, and having its lower end formed with two complementary loops, the open upper ends of which are inclined slightly toward each other, while their closed lower ends are correspondingly separated from each other, and the said loops being located on the opposite sides of an upstanding reach, the upper edge of which is substantially semicircular and formed with a crescent-shaped bevel.

2. As a new article of manufacture, a one-piece double-loop buckle having an upper, a middle, and a lower bar, and having its lower end formed with two complementary loops, the open upper ends of which are inclined slightly toward each other, while their closed lower ends are correspondingly separated from each other, the said loops being located on the opposite sides of an upstanding reach, the upper edge of which is substantially semicircular and formed with a crescent-shaped bevel, and the said buckle having button-guiding lugs located adjacent the open upper ends of the said loops and inclined inward to coact with the bevel of the said reach.

3. As a new article of manufacture, a one-piece double-loop buckle having an upper, a'middle, and a lower bar, and having its lower end formed with two complementary loops, the open upper ends of which are inclined slightly toward each other, while their closed lower ends are correspondingly separated from each other, the said loops being located on the opposite sides of an upstanding reach, the upper edge of which is substantially semicircular and formed with a crescent-shaped bevel, and the said buckle having button-guiding lugs located adjacent the open upper ends of the slots and inclined inward to coact with the bevel of the said reach, and the rear edge of the buckle being struck up to form a coextensive bearing-flange extending at a right angle to its plane and entirely encircling it, save at the high points of the said button- 20 guiding lugs, where it substantially flattens out.
